①Fix 2pcs of hex spacer to the PCB
SIDE-B with 2pcs of binding screw
small.
②Set AC inlet and temporarily fix it
with 2pcs of binding screw small.
③Solder the terminals of AC inlet at
3 locations, on PCB SIDE-A.
④Remove the screws used for
temporary fixation in Step ②

Make sure the
switch is set
closely and
horizontally to
the PCB upon
soldering.
Tilt for 30-45 degree,
not 90 degree.
* The pins may be bent. Adjust them
with long-nose pliers to match PCB
holes before mounting.
Solder the fixing pin as well.
The nut and washer
will be used in a
later step.

Set the LED at the
right angle first, and
solder. Then bend the
leads as shown on
the right.
